We 've already had for some time the sets of AA Performance in our assortment, as an alternative for the always more expensive Mahle cylinder/piston sets. Due to the increasing success of these sets we 've enlarged our assortment with kits for 1200cc (Ø 77mm) Type 1 engines. From now on they are available per kit, consisting of 4 cylinders, pistons, piston axles and clips from our program.
